A study from 2005 claims that high school students are active for 60 minutes a day on average. A researcher believes this has decreased over time. He randomly selects a group of high school students nationwide and determines the group’s average amount of activity to be 50 minutes. If the p-value for this new study is 0.03 and the researcher is using an alpha of 0.05, what should the researcher conclude?
a. There is evidence at the 0.05 level of significance that high school students on average are active for less than 60 minutes a day
b. There is evidence at the 0.05 level of significance that high school students on average are active for more than 60 minutes a day
c. There is evidence at the 0.05 level of significance that high school students on average are active for approximately 60 minutes a day
d. There is not enough information provided to reject or fail to reject the null hypothesis.
